Dentist is in feb but in August when he last went there weren’t any problems. He has been under the weather over xmas which is probably the cause this time but I have noticed it a little in the past too. I’m guessing it’s down to tooth brushing being inadequate. I’m going to watch him tonight. Is it a hormone / growing up thing too? I seem to remember having bad breath around the same age and being told it was due to ‘growing up’ but never really believed it.
